VEHICLE-SPRING'.

Specification of Letters Patent.

Patented Aug. 20,1918.

Application led January 8, 1916. Serial No. 70,948.

To all whom it may concern:

Be it known that I, ARzENo J. DiLLEY, a citizen of the United States, residing at Muir, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a specification.

My invention relates to an improvement in vehicle-springs, and the present invention is an improvement more especially upon the construction set forth in Letters Patent No. 1,137 ,845, granted to me May 4, 1915.

My present invention comprises a plurality of leaf-springs, the outer ends of which have oil depressions formed therein, with communicating ducts to some accessible part of the spring to receive a lubricant, and a felt mat or pad inserted in the depression adapted to retain the oil and keep out dirt, therebyy providing a perfectly lubricated spring which will be simple in parts and construction, easily and cheaply manufactured, and effectual in the performance of its functions.

In the accompanying drawings:

Figure l is a bottom plan View; and

Fig. 2 is a longitudinal sectional View of my improved spring having the felt or absorbent mat or pad in the oil depression at the end.

Fig. 3 is a perspective view of a portion of two leaves of a spring arranged in operative position and illustrating various forms that the pocket may take.

The numerals 1, 1, represent any number of superimposed leaf-springs, the upper of which are successively shorter than the one below in the usual construction in this type of spring, and all of which are connected centrally by the bolt or other securing means 2.

In the outer ends, recesses or depressions 4 are stamped, preferably directly in the metal, as for instance by a displacement, in circular, oblong, or other form (two of which are illustrated) of depression.

From these depressions, ducts 5 preferably lead to the edge of the spring, in the illustrated form, or to the end of the spring, as a means for receiving the lubricant into the depressions or recesses to keep the contacting and otherwise frictionally rubbing ends of the spring 'from undue wear and friction.

A pad or mat 6 of felt or other absorbent material is fitted in each of these recesses and adapted to absorb the lubricant and distribute it economically. This pad or mat also tends to keep out dirt and grit, and thereby facilitates in preserving the antifriction character of the springs at the point wherein the pad or mat is inserted. While the pad or mat might be glued or otherwise secured in place, of course the edges of the depression or recess, together with the closure of the recess or depression by the leaf below, in themselves tend to hold the mat or pad in place.

The absorbent character of the felt or equivalent lamentous material is too well understood to require elaboration. It will suffice to say that by its use the oil is utilized more economically and advantageously. It is concentrated in its application rather than being spread out too freely and perhaps wasted, and resulting in a greasy outer surface, which would tend to catch dust and dirt and cause an unsightly appearance as well as the wasting of the oil, all of vwhich is avoided by the application of this absorbent pad or mat, which as long as it is supported, gives out the required amount of oil or lubricant at the place where its application is required.

I claim:

In a leaf spring, a leaf having a struckup portion adjacent to the free end thereof, said struck-up portion forming a lubricantcontaining ocket, a pad of absorbent material in said3 pocket, and a duct extending from the recess to the end of the leaf for conveying lubricant to the pocket.

In testimony whereof I affix my signature.

ARZENO J. DILLEY.
